For thousands of years, fluffy white dogs could be found across the Pacific Northwest. Their exceptionally soft, crimpy hair was shorn like sheep’s wool, spun into yarn, and woven into blankets and robes by indigenous women who carefully tended them in communities across Coast Salish territory. But a hundred years ago, the woolly dog quietly vanished. Why? Today, the only known pelt of this extinct breed is in the collections of the Smithsonian’s National Museum of Natural History, and it might hold some answers. Through collaborate research combining Western science with Indigenous knowledge, we delve into this animal’s genome to learn the real story of the woolly dog’s disappearance. Guests:Audrey Lin, evolutionary molecular biologist, research associate at the Smithsonian’s National Museum of Natural History and postdoctoral scholar at the American Museum of Natural HistoryLogan Kistler, curator of archaeobotany and archaeogenomics in the anthropology department of the Smithsonian’s National Museum of Natural History Liz Hammond-Kaarremaa, master spinner who studies traditional Salish textiles as a research associate at Vancouver Island University and the Smithsonian’s National Museum of Natural HistorySteven Point / Xwĕ lī qwĕl tĕl, grand chief of the Stó:lō Tribal Council, chancellor of the University of British Columbia, former lieutenant-governor of British Columbia, retired judge, and member of the Skowkale First NationDebra Sparrow / θəliχʷəlʷət, weaver, artist and knowledge-keeper from Musqueam.

Hitch a ride on the Chandra X-ray Observatory as it scours deep space for some of the most enigmatic and misunderstood objects in the universe: black holes. What are they good for? Absolutely something.This is the second episode of a two-part journey celebrating the 25th anniversary of the Chandra X-ray Observatory and the Smithsonian Astrophysical Observatory's operation of the space telescope. Join us this summer for a cosmic journey full of events and virtual resources from around the Smithsonian that will transport you from our closest star, the sun, to the far reaches of the universe.Find the full schedule on our website or follow along on social media @Smithsonian.Guests: Kim Arcand, Visualization Scientist and Emerging Tech Lead for NASA's Chandra X-ray Observatory at the Smithsonian Astrophysical Observatory Daryl Haggard, professor of physics at McGill University in the Trottier Space InstitutePriyamvada Natarajan, astrophysicist and professor at Yale University  

Black holes could unlock the mysteries of creation and live at the heart of nearly every galaxy. But these invisible balls of extremely dense matter have never been fully understood, especially when they were only a theory. We travel through a cosmic wormhole back to the 1930s to learn how the first astrophysicist to successfully theorize a black hole, Subrahmanyan Chandrasekhar, was ridiculed and rejected by his scientific community.This is the first episode of a two-part journey celebrating the 25th anniversary of the Chandra X-ray Observatory and the Smithsonian Astrophysical Observatory's operation of the space telescope. Join us this summer for a cosmic journey full of events and virtual resources from around the Smithsonian that will transport you from our closest star, the sun, to the far reaches of the universe.

The cicadas are back for some fun in the sun, and this time, they’re louder than ever! For the first time since 1803, Broods XIII and XIX will be emerging at the same time, covering the American South and Midwest with trillions of cicadas. As Smithsonian entomologist Floyd Shockley readies his nets for the biggest bug invasion in centuries, we look back at the emergence of Brood X in 2021, and explore how cicadas have captivated our human ancestors for millennia.

Floyd Shockley, entomologist at the Smithsonian’s National Museum of Natural History

"God in a cup." "Perfection." "The world's best coffee." Panamanian geisha coffee has been called many things, but never Smithsonian Bird Friendly certified. That might soon change, however, as researchers from Smithsonian National Zoo and Conservation Biology Institute’s Migratory Bird Center find new ways to grow coffee in harmony with migratory songbirds. Join us for this fully caffeinated romp through Panama’s coffee farms as we learn all about the birds and the beans. 

Guests: 

Ruth Bennett, research ecologist at the Smithsonian National Zoo and Conservation Biology Institute’s Migratory Bird Center

Katherine Araúz Ponce, fellow at the Smithsonian Tropical Research Institute and PhD student at The University of Georgia

Maria Ruiz, owner of Ruiz Coffee Distributors

Ratibor & Aliss Hartmann, owners of Finca Hartmann, specialty coffee and ecotourism

If you’ve bought a plane ticket recently, you’ve probably had the option to pay a few extra dollars to offset your carbon emissions. That money might go toward planting some trees… but how many trees? Researchers at the Smithsonian Tropical Research Institute are trying to answer this very question by hand-measuring trees, weighing wood, and climbing to the top of the canopy. We tag along to see how carbon is measured, and why so much ends up in tropical forests.
